Shimano Alfine Di2 SG S7051-11 Internally Geared Center Lock Disc Rear Hub 11 Speed. Shimano Gear Change Support Mechanism utilizes some portion of pedaling force at down shifting. The result is a quick and precise downshift with very light feeling. For the automatic shifting system, this Gear Change Support Mechanism is the key. Shifting effort is reduced to the point where the hub can be shifted through a small low-torque DC motor. Less electricity is required, so a smaller battery allows the system to be lighter and more compact.
